The Earth's core is the part of Earth in the middle of our planet. It has a solid inner core and a liquid outer core.. Outer core. The outer core of the Earth is a liquid layer about 2,266 kilometers thick. It is made of iron and nickel.This is above the Earth's solid inner core and below the mantle.Its outer boundary is 2,890 km (1,800 mi) beneath the Earth's surface.

Because the Earth's inner core is a solid lump of iron, you may think that it is the source of the Earth's magnetic field. But this is not the case. The Earth's outer core, which consists of molten iron and nickel, flows around the inner core, and this motion produces the magnetic field.
Earth's core facts for kids. Kids Encyclopedia Facts. Structure of Earth. The Earth's core is the part of Earth in the middle of our planet. It has a solid inner core and a liquid outer core. Outer core. The outer core of the Earth is a liquid layer about 2,260 kilometers thick.
What Are Some Interesting Facts About the Outer Core? The outer core, one of the three layers of the Earth, is approximately 1,430 miles (2,300 kilometers) thick and between 7,200 and 9,000 F. According to National Geographic, the outer core is mostly composed of iron and nickel in a liquid alloy form.
Earth's Inner Core Lesson for Kids: Definition & Facts. Chapter 11 / Lesson 76. Lesson; Earth's ... In this lesson we will learn facts about the inner core, as well as how scientists study it.
The inner core is the very center of the Earth, and the hottest part of the planet.It is a mainly solid ball with a radius of about 1,220 km (760 mi), according to seismological studies. It is believed to consist mostly of an iron–nickel alloy and to be about the same temperature as the surface of the Sun: about 5700 K (5400 °C).. The inner core was discovered by Inge Lehmann in 1929, using ...
This lesson will discuss the layers of the Earth, focusing particularly on the Earth's core, including its chemical composition, temperature, and how the core creates the Earth's magnetic field.
The center of the Earth is made up of two layers, the outer core and the inner core. The outer core is the third layer of the Earth. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth’s magnetic field.As Earth spins on its axis, the iron inside the liquid outer core moves around.
Three layers of the Earth are The Core, The Mantle and The Crust. These three layers are further divided into a number of sub-layers like oceanic and continental crust, upper and lower mantle and outer and inner core. So let's check out each of these in detail in Layers of the Earth for kids.
